An idyllic family vacation is unexpectedly thrown into jeopardy with the arrival of an amiable visitor whose casual disregard for the family mold causes a notable rift in the once-happy household in director Zabou Breitman's assured sophomore feature. Frédéric (Bernard Campan) is a middle-class father whose deep love for both his beautiful wife Frédérique (Léa Tucker) and their energetic son makes the perfect snapshot of modern contentment. Each day of their sun-soaked vacation seems to pass with the gentle flow of a refreshing breeze as the carefree trio swims, dines on the terrace, and simply enjoys their time together. When recently arrived neighbor Hugo (Charles Burling) drops by for a visit, good natured Frédéric generously invites the man to join his family for dinner. Their casual dinner conversation soon leading to the revelation that Hugo is gay, Frédéric and Hugo subsequently develop a warm friendship despite their drastically different lifestyles. In the days that follow, the deeply personal conversations between longtime monogamist Frédéric and free-thinking Hugo send the once-lazy family vacation into unexpectedly introspective territory as the sexually static father and husband gradually begins to question his longstanding beliefs about human relationships.
